SSD Performance Atto Disk Benchmark
Atto Disk Benchmark
One of the finest tools available for gauging storage performance is ATTO. I love it to death, as it is so reliable and produces such accurate results. The great thing about ATTO is that we use it for tests with predefined block sizes. So, we can test with a 32 MB sequence of 4 KB files, yet also with 32 MB in 1 MB files. This gives us an excellent scope of overall performance with small and large files.
The most important and difficult task for any storage unit is writing really small files fast, so have a look at that in this WRITE test. We scale 4 KB block sizes to 1024 KB block sizes in bursts of 256 MB with a large queue depth and then measure how fast the storage device deals with them.
